Reports library function calls which could be replaced by simplified one.
<p>Using corresponding functions makes your code simpler.</p>
<p>The quick-fix replaces the function calls with another one.</p>
<p><b>Example:</b></p>
<pre><code>
  fun test(list: List&lt;Any&gt;) {
      list.filter { it is String }
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  fun test(list: List&lt;Any&gt;) {
      list.filterIsInstance&lt;String&gt;()
  }
</code></pre>
